What I'm looking for

I'm looking to build scalable backend systems, full-stack web applications, or cross-platform mobile solutions in an Agile team where I can contribute to impactful products and continue growing in .NET, Python, cloud, and data-driven development.

I've built backend services for SIDMACH Technologies' eStudy educational platform, serving 10,000+ active users through ASP.NET Core Web API, C#, and SQL Server.

I developed a Text-to-Speech module that reads WAEC exam questions, answers, and explanations aloud, improving accessibility for disabled candidates. I also built gamification features for peer challenges and competitive quizzes, helping drive engagement and retention.

My work spans RESTful APIs, Entity Framework Core, Dapper, WebSockets, WinForms support, database optimization, and role-based access control. I have also built agricultural marketplace, school portal, and RFID-powered IoT attendance solutions.

I'm comfortable collaborating in Agile teams through stand-ups, code reviews, sprint planning, demos, and Scrum-based delivery.
